CAR-REPLACER.

Specification of Letters Patent. Patented Jan. 31, 1911.

Application filed. August 3, 1910. Serial No. 575,273.

To all whom it may concern:

Be it known that I, F RANK B. PLASKO, citizen of the United States,residing at Norwalk, in the county of Huron and State of Ohio, haveinvented certain new and useful Improvements in Car-Replacers, of whichthe following is a specification.

This invention relates to car replacers, or so called wrecking frogs,and has for its ob ect to provide an improved device for replacing carson the rails of a railway track.

The invention comprises a block with an inclined part up which the wheelcan travel to the rail, and novel means for retaining the block inposition on the rail, said means including a hook forming part of theblock and a two part wedge which retains the block in place and whichwill tighten under longitudinal pressure when the block is engaged bythe car wheel.

The invention is hereinafter described and is illustrated in theaccompanying drawings in which Figure 1 is a top plan view of thedevice. Fig. 2 is an elevation of one side. Fig. 3 is a elevation of theother side. Fig. 4. is a bottom view of the device removed from therail. Figs. 5 and 6 are opposite end views of the device. Figs. 7 and 8are respectively side and top views of the wedge for holding the devicein place.

Referring specifically to the drawings, the block has an inclined part 7to receive the tread of the rail, and at one edge of this part is aflanged piece 8 which projects above the top surface of the tread partand serves to guide or confine the wheel on said tread part. At theother edge of the part 7 is a triangular part 6 the surface of which islower than the tread part 7, forming a shoulder at 10 to guide the wheelflange. The side edge 11 of the part 6 is inclined or extends at anangle to the main block, to fit closely against the side of the rail 12.These parts 6 and 7 are rounded or inclined downwardly as indicated at13, at the end where the wheel mounts the block, and the tread part '7may be strengthened by a longitudinal rib 14 thereunder. At the upperend of the block a hook 9 projects from the side of the tread part 7, atthe edge thereof opposite to the flange 8, and said hook 9 is shaped toengage over the head of the rail and under said head on the side thereofopposite to the main part of the block when the latter is applied to therail. The function of this hook is to hold the block to the rail and toretain the same in proper position to produce the result desired. As afurther retaining means I provide a double wedge shown particularly inFigs. 6, 7 and 8. This consists of two sections 15 and 16 whichinterlock with each other by means of a rib 17 on the section 15 fittingin a groove 18 on the section 16, the meeting surfaces of the sectionsbeing inclined to one another to produce a wedge action. This wedge isproperly shaped and constructed to fit between the web of the rail and alug 19 depending on the underside of the tread part 7 at the upper endthereof, as particularly shown in Fig. 3, the face of the lug 19 on theside toward the rail being flattened to fit against the side of the part15 of the wedge, the section 16 of the wedge being fitted against therail web. The rib 17 is preferably dovetailed, to hold the wedgesections together.

In the use of the device, the block is applied to the rail with the hook9 engaged over the head thereof. The wedge is then applied and tightenedby tapping up the parts, the pressure against the lug 19 drawing thehook 9 to tight engagement with the head of the rail. The block isthereby supported in the proper inclined position to receive the carwheel and allow the same to travel up the tread part of the block to therail, the flange of the wheel running up along the shoulder 10 andthence over the hook 9, to the inside of the rail.

The devices will be made rights and lefts, so as to be capable of use onboth rails of the track. To release the device it is simply necessary toloosen the wedge by tapping on the end of one of the sections thereof.The device may be very easily and quickly attached, without theinconvenience and delay of using spikes or other objectionable fasteningdevices to hold the replacer in position.

Having thus described my invention,
